The built-in download manager of
firefox 35 has a long list of missing features including such a basic like download and upload data rate throttling. There're a lot of download managers available as complementary add-ons which don't interact with the built-in download manger (they can't be used when a download link is clicked on and/or need to be started explicitly when previous downloads ought to be resumed - when the downloads allow it). Further problems include duplicate configuration and traffic loss (when a download is started in one manager and requires features which are only available in the other and needs to be restarted). I am looking for a solution which is not based on a concept which immanently wastes my time (as described above), i.e. an manager which integrates with the build-in manager or disables it efficiently (including settings synchronization). I checked
- Download Manager Tweak 1.0.8: doesn't integrate with built-in download manager, at least not with All-in-one Sidebar 0.7.25 installed; throttle features not checked
- Modern Download Manager 0.2.1: integrates will with built-in download-manger and All-in-one Sidebar 0.7.25, but doesn't have any visible or accessible features
and gave up because it became a trial-error-search.
A solution in form of an extension would be nice, but is not a requirement (I just can't imagine another solution).
